Powerful desktop multiprocessor systems based on the Intel Architecture (iA) offer a formidable alternative to traditional scientific/engineering workstations for commercial application developers at an attractive costperformance ratio. However, the lack of adequate compiler and runtime library support for multithreading and parallel processing on Windows NT* makes it difficult or impossible to fully exploit the performance advantage of these multiprocessor systems. In this paper we describe the design, development, and initial performance results of the Illinois-Intel Multithreading Library (IML), which aims at providing an efficient and powerful (in terms of types of parallelism it supports) API for multithreaded application developers.

This document is an update to the 1994 Quality and Reliability Roadmap issued in support of the 1994 National Technology Roadmap for Semiconductors. This report revisits the challenges, constraints, priorities, and research needs pertaining to quality and reliability issues. It also provides key project proposals that must be implemented to address concerns about reliability attainment and defect learning. An expanded section on test-to-test, diagnostics, and failure analysis; an edited version of the Product Analysis Forum Roadmap; and an appendix containing a draft report highlighting reliability issues is included.

Circuit simulation is a necessary everyday tool to circuit designers who need to constantly verify and debug their circuits during the design process. As engineers face larger, more complex designs and tighter project schedules, fast SPICE simulation with no loss in accuracy has become a necessity. Simulation indeed accounts for a large portion of the time spent in the design and optimization of a new circuit...

In response to a growing concern within the Electronic Industry to the transition to Halogen-Free laminates (HFR-Free) within the Client Market space (Desktop and Notebook computers) iNEMI initiated a HFR-Free Leadership Workgroup to evaluate the readiness of the Industry to make this transition. The HFR-Free Leadership WG concluded that the electronic industry is ready for the transition and that the key electrical and thermo-mechanical properties of the new HFR-Free laminates can meet the required criteria. The HFR-Free Leadership WG verified that the laminate suppliers can meet the capacity demands for these new HFR-Free laminates and developed a "Test Suite Methodology" (TSM) that can facilitate the comparison and choice of the right laminate to replace brominated FR4 in the Client space...

This paper discusses solder paste printing and flux dipping assembly processes for 0.4 and 0.5mm pitch lead-free WLCSPs and the corresponding assembly results and thermal cyclic reliability obtained. Variables evaluated include reflow ambient, paste type, and stencil design. Reliability is also compared to results for the same components assembled under identical conditions using SnPb solder.

Commercial-off-the-shelf ball/column grid array packaging (COTS BGA/CGA) technologies in high reliability versions are now being considered for use in a number of National Aeronautics and Space Administration (NASA) electronic systems. Understanding the process and quality assurance (QA) indicators for reliability are important for low-risk insertion of these advanced electronic packages. This talk briefly discusses an overview of packaging trends for area array packages from wire bond to flip-chip ball grid array (FCBGA) as well as column grid array (CGA). It then presents test data including manufacturing and assembly board-level reliability for FCBGA packages with 1704 I/Os and 1-mm pitch, fine pitch BGA (FPBGA) with 432 I/Os and 0.4-mm pitch, and PBGA with 676 I/Os and 1.0-mm pitch packages.
